I started taking 10mg Paroxetine 3 weeks and 4 days ago. For the first two weeks I had all of the nasty side effects on a daily basis. Then it stopped and the meds started working and I felt great for about 5 days, then out of the blue without warning a couple of days ago I suddenly had a very bad panic attack and after that I now again am experiencing the side effects of the meds. How long before this meds start working and the side effects go away and will the 10mg help for my panic disorder and OCD? I just want to mention that I was on 20mg about 3 years ago and it worked great. It was amazing. I remember it also took about 4 - 5 weeks before it kicked in. I used it for about 5 months and then stopped. I dont want to use more than 10mg per day.
